Release Notes
=============
#. VPP PERFORMANCE TESTS
- - CSIT test environment is versioned, see
- :ref:`test_environment_versioning`.
-
- - **GENEVE tests**: Added VPP performance tests for GENEVE tunnels.
- See :ref:`geneve_methodology` for more details.
-
-
- - **GSO tests**: Added VPP performance tests for GSOtap and GSOvirtio.
- All tested topologies are compared with GSO enabled and disabled.
- In |csit-release| there is only 1t1c tests running.
- See :ref:`gso_methodology` for more details.
-
+ - **Added new performance testbed 3n-snr** (3 Node SnowRidge, with Intel
+ Atom processors).
- - **NAT44 tests**: Added new test type, pure throughput tests.
- They are similar to PPS tests, but they employ ramp-up trials
- to ensure all sessions are created (and not timing out)
- for performance trials.
+ - **Added GTPU HW offload tests** using VPP GTPU hardware offload
+ with Intel e810 4p25ge NICs (3n-icx testbeds only). These tests
+ were already there in CSIT-2206, but were yielding invalid
+ results due to using TRex v2.97 that was incompatible with e810
+ NICs used for those tests.
- - **Jumbo for ipsec**: Test cases with 9000 byte frames are re-enabled
- in ipsec suites.
+ - **Added Wireguard tests** using VPP software crypto (3n-icx, 3n-snr
+ testbeds) and using built-in hardware crypto QAT device (3n-snr testbed
+ only).
- - **Randomized profiles**: Improved repeatability and cycle length.
- For details, see :ref:`packet_flow_ordering`.
-
- - **Arm 2n-tx2 testbed**: New physical testbed type installed in
- FD.io CSIT, with VPP and DPDK performance data added to CSIT
- trending and this report.
-
- - **Framework speedup**: Shortened overall test job duration
- by using a different test selection mechanism (using --test
- instead of --include) and by avoiding unnecessary PAPI reconnects.
+ - **Reduction of tests**: Removed certain test variations executed
+ iteratively for the report (as well as in daily and weekly
+ trending) due to physical testbeds overload.
#. TEST FRAMEWORK
- - **TRex ASTF**: Improved capability to run TRex in advanced stateful mode.
+ - CSIT-2210 executes all VPP v22.10 performance tests using vpp ubuntu2204
+ images, due to CSIT execution environment change as noted below. This
+ applies to all performance testbeds except Denverton. Consequently, VPP
+ v22.06 has not been re-tested in CSIT-2210 environment, as no ubuntu204
+ images are available for that VPP version. Performance comparison
+ between VPP v22.10 (current version) vs VPP v22.06 (previous version)
+ may be impacted by VPP build environment change (ubuntu2004 to ubuntu
+ 2204) change and CSIT environment change. See :ref:`vpp_rca` for
+ details.
+
+ - **CSIT test environment** version has been updated to ver. 11, see
+ :ref:`test_environment_versioning`.
- - **CSIT PAPI support**: Due to issues with PAPI performance, VAT is
- still used in CSIT for all VPP scale tests. See known issues below.
+ - **TCP TPUT profiles** had to be changed, as newer TRex versions
+ are not deterministic enough when deciding when to send an ACK.
- - **General Code Housekeeping**: Ongoing code optimizations,
- speed ups and bug fixes.
+ - **CSIT PAPI support**: Due to issues with PAPI performance, and
+ deprecation of VAT, VPP CLI is used in CSIT for many VPP scale
+ tests. See :ref:`vpp_known_issues`.
+
+ - **General Code Housekeeping**: Ongoing code optimizations and bug
+ fixes.
#. PRESENTATION AND ANALYTICS LAYER
- - **Graphs improvements**: Updated Packet Latency graphs,
- see :ref:`latency_methodology`.
+ - **C-Dash** `performance dashboard <http://csit.fd.io/>`_ got updated UI and
+ updated backend increasing its performance and robustness.

+| # | JiraID | Issue Description |
++====+=========================================+===========================================================================================================+
+| 1 | `CSIT-1782 | Multicore AVF tests are failing when trying to create interface. |
+| | <https://jira.fd.io/browse/CSIT-1782>`_ | Frequency is reduced by CSIT workaround, but occasional failures do still happen. |
++----+-----------------------------------------+-----------------------------------------------------------------------------------------------------------+
+| 2 | `CSIT-1785 | NAT44ED tests failing to establish all TCP sessions. |
+| | <https://jira.fd.io/browse/CSIT-1785>`_ | At least for max scale, in allotted time (limited by session 500s timeout) due to worse |
+| +-----------------------------------------+ slow path performance than previously measured and calibrated for. |
+| | `VPP-1972 | CSIT removed the max scale NAT tests to avoid this issue. |
+| | <https://jira.fd.io/browse/VPP-1972>`_ | |
++----+-----------------------------------------+-----------------------------------------------------------------------------------------------------------+
+| 3 | `CSIT-1799 | All NAT44-ED 16M sessions CPS scale tests fail while setting NAT44 address range. |
+| | <https://jira.fd.io/browse/CSIT-1799>`_ | |
++----+-----------------------------------------+-----------------------------------------------------------------------------------------------------------+
+| 4 | `CSIT-1800 | All Geneve L3 mode scale tests (1024 tunnels) are failing. |
+| | <https://jira.fd.io/browse/CSIT-1800>`_ | |
++----+-----------------------------------------+-----------------------------------------------------------------------------------------------------------+
+| 5 | `CSIT-1801 | 9000B payload frames not forwarded over tunnels due to violating supported Max Frame Size (VxLAN, LISP, |
+| | <https://jira.fd.io/browse/CSIT-1801>`_ | SRv6). |
+----+-----------------------------------------+-----------------------------------------------------------------------------------------------------------+
-| 2 | `VPP-662 | 9000B packets not supported by NICs VIC1227 and VIC1387. |
-| | <https://jira.fd.io/browse/VPP-662>`_ | |
+| 6 | `CSIT-1802 | all testbeds: AF-XDP - NDR tests failing from time to time. |
+| | <https://jira.fd.io/browse/CSIT-1802>`_ | |
+----+-----------------------------------------+-----------------------------------------------------------------------------------------------------------+
-| 3 | `CSIT-1763 | Adapt ramp-up phase of nat44 tests for different frame sizes. |
-| | <https://jira.fd.io/browse/CSIT-1763>`_ | Currently ramp-up phase rate and duration values are correctly set for tests with 64B frame size. |
+| 7 | `CSIT-1804 | All testbeds: NDR tests failing from time to time. |
+| | <https://jira.fd.io/browse/CSIT-1804>`_ | |
+----+-----------------------------------------+-----------------------------------------------------------------------------------------------------------+
-| 4 | `CSIT-1671 | All CSIT scale tests can not use PAPI due to much slower performance compared to VAT/CLI (it takes much |
-| | <https://jira.fd.io/browse/CSIT-1671>`_ | longer to program VPP). This needs to be addressed on the PAPI side. |
-| +-----------------------------------------+ The usual PAPI library spends too much time parsing arguments, so even with async processing (hundreds of |
-| | `VPP-1763 | commands in flight over socket), the VPP configuration for large scale tests (millions of messages) takes |
-| | <https://jira.fd.io/browse/VPP-1763>`_ | too long. |
+| 8 | `CSIT-1808 | All tests with 9000B payload frames not forwarded over memif interfaces. |
+| | <https://jira.fd.io/browse/CSIT-1808>`_ | |
+----+-----------------------------------------+-----------------------------------------------------------------------------------------------------------+
-| 5 | `VPP-1934 | [i40e] Interfaces are not brought up from carrier-down. |
-| | <https://jira.fd.io/browse/VPP-1934>`_ | In case of i40e -based interface (e.g Intel x700 series NIC) is bound to kernel driver (i40e) and is in |
-| | | state "no-carrier" (<NO-CARRIER,BROADCAST,MULTICAST,UP>) because previously it was disabled via |
-| | | "I40E_AQ_PHY_LINK_ENABLED" call, then VPP during initialization of AVF interface is not re-enabling |
-| | | interface link via i40e driver to up. |
-| | | CSIT implemented `workaround for AVF interface <https://gerrit.fd.io/r/c/csit/+/29086>`_ until fixed. |

++----+-----------------------------------------+-----------------------------------------------------------------------------------------------------------+
+| 12 | `CSIT-1864 | 2n-clx: half of the packets lost on PDR tests. |
+| | <https://jira.fd.io/browse/CSIT-1864>`_ | |
++----+-----------------------------------------+-----------------------------------------------------------------------------------------------------------+
+| 13 | `CSIT-1877 | 3n-tsh: all VM tests failing to boot VM. |
+| | <https://jira.fd.io/browse/CSIT-1877>`_ | |
++----+-----------------------------------------+-----------------------------------------------------------------------------------------------------------+
+| 14 | `CSIT-1883 | 3n-snr: All hwasync wireguard tests failing when trying to verify device. |
+| | <https://jira.fd.io/browse/CSIT-1883>`_ | |
++----+-----------------------------------------+-----------------------------------------------------------------------------------------------------------+
+| 15 | `CSIT-1884 | 2n-clx, 2n-icx: All NAT44DET NDR PDR IMIX over 1M sessions BIDIR tests failing to create enough sessions. |
+| | <https://jira.fd.io/browse/CSIT-1884>`_ | |
